Questions
How big is the Hey PCB?
It measures 24 × 48.5 mm and has 2 copper layers, 0.41 mm thick.
What parts does the Hey use?
40 parts, built around the W25Q128JVSIQ, AMS1117 and UK-B0206-G5-160-JZ. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Hey KiCad files?
From the dwan6767/BeepBop repository on GitHub, at the commit this page was made from: the board is hypergrey/hardware/hey.kicad_pcb and its schematic hypergrey/hardware/RP2040.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hey design in my own project?
Its repository states no licence, so its author keeps all rights: ask dwan6767 before reusing the design.
